I don't think any of the chips you see on there will be a full AMD 3 year warranty. Most are OEM 15 or 30 day warranties. This was a listing on Pricewatch that offered an OEM witha 1 year warranty, which I consider pretty good. <A HREF="http://www.lynncomp.com/shop3/" target="_new">http://www.lynncomp.com/shop3/</A>
You usually have to look at the seller's website and I even take a step further and usually give them a call just to make sure. Just make sure you're getting what you're paying for.
